I've not had an issue with FastTech. Many orders made and received! When there was a problem, they took care of it ASAP, and everything is warrantied. If it is not working as designed, return it. Waiting for the latest order now of another starter kit for a friend.
While I agree that Much of FT's stuff is low quality and knock offs, that is not true of Everything. You can't willy nilly pick an item just due to cost and expect the best in return. Many of the higher priced items are very good, and still lower priced than other places. Many knock offs are great and work better than the originals.. But again, not everything is perfect.
The juice is the same you can get anywhere, names that many of us have used since we started vaping. Some is OEM, made to be rebranded, some is named and some I wouldn't touch! LOL
Free shipping, warranties, low prices. That's good enough for me, and if I ever have an issue with something I get, I will speak out about it!
